Probing acceleration and turbulence at relativistic shocks in blazar jets [PDF]

, 2016
Diffusive shock acceleration (DSA) at relativistic shocks is widely thought to be an important acceleration mechanism in various astrophysical jet sources, including radio-loud active galactic nuclei such as blazars. Such acceleration can produce the non-

Effect of Background Magnetic Field on Ion Weibel Instability With High‐Intensity Short‐Pulse Lasers

Contributions to Plasma Physics, Volume 65, Issue 10, November 2025.
ABSTRACT The effect of finite background magnetic field on magnetic field amplification by Weibel instability using high‐intensity short‐pulse lasers is investigated. We consider Weibel instability for counter‐streaming sub‐relativistic plasma flows generated by shooting pure carbon targets with short‐pulse lasers.

Precursors and Main-bursts of Gamma Ray Bursts in a Hypernova Scenario

, 2005
We investigate a "hypernova" model for gamma-ray bursts (GRBs), i.e., massive C+O star model with relativistic jets. In this model, non-thermal precursors can be produced by the "first" relativistic shell ejected from the star.

SPATIAL GROWTH OF THE CURRENT-DRIVEN INSTABILITY IN RELATIVISTIC JETS [PDF]

, 2014
We investigated the influence of velocity shear and a radial density profile on the spatial development of the current-driven (CD) kink instability along helically magnetized relativistic jets via three-dimensional relativistic magnetohydrodynamic ...

Electron Density Structure Measurements With Scattered Intense Laser Beam

Contributions to Plasma Physics, Volume 65, Issue 10, November 2025.
ABSTRACT Short‐pulse intense lasers have the potential to model extreme astrophysical environments in laboratories. Although there are diagnostics for energetic electrons and ions resulting from laser‐plasma interactions, the diagnostics to measure velocity distribution functions at the interaction region of the laser and plasma are limited.

A Probabilistic Model for Global EMIC Wave Activity Using Van Allen Probes Observations

Earth and Space Science, Volume 12, Issue 11, November 2025.
Abstract Electromagnetic ion cyclotron (EMIC) waves play a key role in radiation belt dynamics through resonant interactions. However, their low occurrence probability, high variability, and spatial intermittency pose challenges for accurate modeling.

Simulations of Electron Interaction With Ionospheric Alfvén Resonator in the Jovian Aurora

Journal of Geophysical Research: Space Physics, Volume 130, Issue 11, November 2025.
Abstract Recently, Lysak et al. (2021, https://doi.org/10.1029/2021ja029886) modeled the formation of the Ionospheric Alfvén Resonator (IAR) in Jovian aurora and demonstrated the generation of a small structure perpendicular to the magnetic field and a parallel electric field E‖ $\left({E}_{\Vert }\right)$ in the low‐density region.

Large Radiation Belt Drift Phase Structuring: Observation and Interpretation of the 19 September 2014 Event

Journal of Geophysical Research: Space Physics, Volume 130, Issue 11, November 2025.
Abstract Prompt radial transport of trapped energetic particles can leave transient marks in radiation belt intensity in the form of drift phase structures. Drift phase structures are local extrema in spectrograms that propagate in space following the drift paths of trapped particles.

Relativistic plasmas in AGN jets - From synchrotron radiation to $\gamma$-ray emission

, 2017
Relativistic jets of plasma are a key ingredient of many types of Active Galactic Nuclei (AGN). Today we know that AGNs are powered by the accretion of inter stellar material into the gravitational field of a Super Massive Black Hole and that this ...
